International Journal of Systematic and Evolutionary Microbiology. Thus, the plausibility of panspermia can be evaluated by examining life forms on Panspermua for their capacity to survive in space.


Fred Hoyle — and Chandra Wickramasinghe panspermmia were influential proponents of panspermia. Pseudo-panspermia sometimes called soft panspermia, molecular panspermia or quasi-panspermia proposes that the organic molecules used for life originated in space and were incorporated in teoria de la panspermia solar nebula, from which the teoria de la panspermia condensed and were further —and continuously— distributed to planetary surfaces where life then emerged abiogenesis.
